T0 at whom itmay concern.-

Be it known that I, LEO G. HEIST, a citizen of the United States, residing at Philadelphia,

in the county offPhiladelphia and State of- Pennsylvania,have invented certain new and 1 tubular base of the burner, preferably semi- Zcircula'r'in'form and provided with burnerfbeads 2 and with starting-cups 3. the 'ends'of'the base may be provided with useful Improvements in Hydrocarbon-Vapor Burners; and I do declare the following'to be a full, clear, and exact description of'theinvention, such as will enable others skilled in" the art to which it appertains to make and use the same. p i The invention relates to hydrocarbon-vapor burners.

The object of the invention isto provide a burner of this character which shall be sim;

ple of construction, durable in use','compara-" tively inexpensive ofproduction, efiicient in action, and one which will generate a maximum amount of heat at the expenditure of a minimum amount of fuel.

With these and other objects in viewthe invention consists of certain novelfeatures burner-heads, the tubularbase, and the gen-J erating-chamber on the line ww'of Fig. etand' looking in the direction of the arrow Fig. 3 is a similar view through the gas-outlet duct, the valve controlling-the escape ofg-as therethrough, and the means for actuating; said valve, said view being'taken on lineyy' of Fig. 4 looking in the direction of the arrow 1). Fig. 4: is a transverse vertical section through the generating-chamber and the oilinletduct and gas-outlet duct, said view being taken on line as of Fig. 3 looking in the direction of the arrow 0. Fig. 5 is a horizontal section through the generating-chamber on the dotted line 0b a of Fig. 4 looking in the direction of the arrow c. Fig. dis a detail perspective view of the valve located in the trapchamber with which the generatingchamber communicates. Fig. 7 is a vertical sectional view through said valve and its valve-seat, showing the relation of parts. Fig. 8 is a detail perspective view of the 'li'shed.

valvesfor controlling the supply of gas to the starting-cup.

Referring to the drawings, 1 denotes the If desired,

remov'able'plugs 4:, which when removed will Ipermit of the'attachment to the ends of said base of an indefinite number of burnerheads 5 (shown in dotted lines in Fig. 1) to increase the heating capacity of the burner. The starting-cups 3 are preferably cast inte* gral with the base and are provided with cenas well as the plug; for repair or other purposes. I i V "11 denotes a gas-generating or vaporizing chamber.

12denotes a stem,fand13 a trap-chamber,

the latter establishing communication between the generating-chamber and the stem.

The stem 'is externally screw-threaded at its lower endto engage an interiorly-screw- 'i's connectedfto the tubular base and the communication between the two parts estab- The generating-chamber is arranged immediately over the burner-heads and is provided with an inlet-duct 15, which communio ca'tes with a tortuous passage 16, which in turn communicates through theoutlet-duct 17 with the trap-chamber 13. The stem is provided with two vertically-disposed passages 18 and 19, through the. former ofwhich 5 extends an oil-inlettube 2,0 of m-uchlless diameter than the passag'e 18,"and jhas its end bent over and"projecting into the duct 15 at a point above the base of the tortuous passage 16, as clearly shown in Figs. ljand 5. The pasroo sages 18 and 19 maybe properly termed, respectively,the inlet-passage to and the out at-passage from the generating-chamber, in hat the oil is carried through the passage 18 o the generating-chamber and escapes from he generating-chamber through the passage 9. It is not absolutely necessary that the ube 20 be employed; but the same is preerred in that it serves to discharge the oil nto the generating-chamber under pressure n the form of a jet, and thereby render it iore susceptible of vaporization.

The trap-chamber is provided with a screwhreaded plug 2l,which has a screw-threaded ngagement with said chamber and is proided with a head 22, by means of which it my be screwed in place. This plug is proided with a tapering valve-seat 23 and with apering jet-orifices 24. denotes a cap or lug screw-threaded at the top of the traphamber directly above the plug 21 and by Jeans of which said plug 21 may be removed hen desired. It will be noticed that the pper end of the plug 21 projects above the ottom of the chamber and that the outletuct 17 from the generating-chamber is be- )w the upper end of said plug. Thus a trap i formed whereby any sediment orgrit leavig the generating-chamber is caught and revented from escaping through the jetrifices 24 with the gas. This foreign matter lay be removed from the trap by unscrewig the plug 25, thus affording access to said 'apchamber.

26 denotes a valve for con trolling the flow E gas from the trap-chamber, and 27 deoles the valves for controlling the supply of as to the burner-heads. The valve 20 is tpered in form to correspond to the tapered wire-seat 23 and is preferably provided with bs :33 to correspond to guide-grooves 29, named in the side walls of the valve-seat. he valve has projecting from its upper end hat I shall term clearance needles or )ints 29, which are adapted to free the it-orifices 24 from carbon, grit, or any other )reign deposit, and thus keep the same in roper condition for the free flow of gas lerethrough. The valves 27 are tapered in mm to correspond to the valve-seats 3 and e provided with clearance-needles or points i for keeping the jet orifices 9 free of grit, trbon, orother foreign matter. These valves have chambers 26, forming bases, fora pur- )se hereinafter to appear. The valve 26 is ninected to a valve-stem 27 by a screw 28 other suitable means, and this stem 27 has nnected to it a bar 29", which is curved to nrrespond with the tubular base 1. The Live-stem 27 is located within the passage and the bar 29 is located within the tullar base and supports the valves 27 and connected thereto in the following manner: he ends of the bar 29 are provided with rews 30, the heads of which project uptrdly within the chambers 26% A screwud 31 extends through the side wall of each amber within the path of movement of the head of the screw 30, so that when the bar 29 is elevated to close the flow of gas through the jet-orifices by the needles or points 26 should said valve adhere to its seat or the needles in the walls of the jet-orifices in the downward movement of the Valve the head of the screw 30 will strike the inner end of the screw 31 and will draw said valve from its seat and the needles from engagement with the walls of the jet-orifices. These valves are directly opposite the plugs 4 of the base, so that when said plugs are removed the screw 31 may be applied to connect said valves to the bar.

33 denotes a tubular extension projecting from the side of the stem 12, and 34 denotes a plug screwed into said extension and provided with a screw-threaded aperture 35. 36 denotes a screw-shaft integral with said plug and provided with a crank orjeccentric pin 37, which projects into a slot 33, formed in the edge of the stem 27. This shaft has a smooth enlarged portion 39, which rotates in a hearing 40 and is formed with a disk 41, which alternately engages the end of the plug 34 and the base of the tubular extension 33 in the opening and closing of the valves, and thus forms a gas-tight joint and prevents the escape of gas at these points. The outer end of the shaft may be provided with a handwheel 44 or other suitable means for rotating it.

42 denotes plugs for closing the ends of the generating-chamber after the core has been removed, and 43 denotes a plug for closing the hole through which a tool is adapted to be inserted to bend down the end of the tube or pipe 20.

The operation of the burner is as follows: The starting-cups are first filled with oil in any suitable manner and from any suitable source of supply and the oil ignited. The flame from this oil will heat the generatingchamber and vaporize or cremate the oiltherein, so that when the valves are open the vapor will be supplied to the burner-heads in a steady uniform manner. It will be observed that the oil will be quickly cremated, due to the fact that the generating-chamber is immediately over the upper ends of and located a short distance above the burner-heads, and that the vapor thus generated is freed from foreign matter before it enters the passage 19 by reason of the fact that it must first pass through the trap-chamber, so that when the vapor is furnished to the burner-head it is in the best possible condition for consumption. It will also be observed that in the act of closing the valves the jet-orifices are automatically cleaned of any accumulated foregn matter, so that when said valves are opened they are in proper condition to perform their functions.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and adburner-heads communicating therewith, of a generating-chamber located above the burnerheads, a stem provided with inlet and outlet passages, the latter of which communicates with the tubular base, a trap-chamber estab-' lishing communication between the outletpassage of said stem and the generating-chamber, saidinlet-passage communicating with the generating-chamber, and means for controlling the fiow of vapor from the generatingchamber to the burner-heads, said means comprising valves, one located in the trap-chamber and the others at the burner-heads'and means for simultaneously operating said valves, substantially as set forth.
